Title: Method and device for controlling thickness of powder layer for continuous casting
Inventor: SASAME KINGO
IPC: B22D11/108
Filed: 1994-08-25
Abstract: PURPOSE: To automatically control the layer thickness of powder to an arbitrary thickness by obtaining the layer thickness of the powder from the difference, between the upper surface level of the mold powder and the surface level of molten steel and supplying the powder based on the difference between this value and the aimed value. CONSTITUTION: The upper surface level of the mold powder and the surface level of the molten steel are always measured with a molten metal surface level meter, such as γ-ray level meter 10 and over current level meter, to detect the layer thickness of the powder with a control unit 12. In the case of the powder layer thickness measured value L < the powder layer thickness aimed value LO, the mold powder PO is charged into the mold 1 from a powder supplying machine 5. In the case of L>LO the powder supply from the powder supplying machine 5 is stopped. By this method, the powder layer thickness during casting is automatically controlled to the arbitrary constant level and the unevenness of the slab surface quality is restrained.  Further, restrained breakout, etc., caused by the shortage of the powder, i.e., insufficient lubrication of the powder melting layer is prevented, and also, the variation of consumption of the powder can continuously be observed.

Title: Cylinder for molding machine
Inventor: TAKADA SHIRO
IPC: B29C47/66
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To facilitate shrinkage fitting work of a cylinder for a molding machine and to prevent fracture of an inner layer member near to the end part on the outlet side and also to enable regeneration of the cylinder and to prevent generation of a crack in an external cylinder. SOLUTION: In the cylinder for a molding machine, an external cylinder 1 is formed into a straight shape and the outside diameter of an inner layer member 2 in a region (zone A) on the outlet side from a charge port of molding material is enlarged. Thereby, shrinkage fitting rate of its part is made larger than shrinkage fitting rate in the region on other side and the inner layer member 2 is stuck to the external cylinder 1 by shrinkage fit. The shrinkage fitting rate of the zone A is made large and the shrinkage fitting rate on other side is made small and a clearance between the cylindrical external cylinder 1 and the inner layer member 2 is comparatively secured in the region excepting the region on the outlet side from the charge port of the molding material at time of shrinkage fitting work. Therefor, positioning of the inner layer member does not necessitate high precision.  Even if the inner layer member is thermally expanded by heat effect of the external cylinder 1 at time of insertion, possibility coming into contact with the inside of the external cylinder is made little and shrinkage fitting work is made easy.

CONSTITUTION:Soft thermoplastic synthetic resin is molded by a die 15 into a hollow parison 20. Both ends of this parison 20 are pinched by a mold 16 and a mold 17, and the parison is blow-molded, whereby the soft blow-molded skin 1 of the decorative molding for an automobile, is obtained. The lower bottom surface 3 of the blow-molded skin 1 is molded with the inner surface 18 of the mold 16 and its projected part 5 is molded with the recessed hole 18a of the mold 16, and it presents almost cylindrical shape. This projected part 5 is removed from the bottom surface 3 with a cutter by moving it in such a manner as transferring locus 6. When the foamable resin material as injecting material 8 or other filling agent, etc. is injected in the cut port 7 obtained on the bottom surface 3, the shape of the skin is kept, whereby the releif for external force becomes small, and post working becomes easy.

Filed: 1989-08-04
Abstract: PURPOSE:To prevent destruction of stored information of non-access cell at accessing by providing a means controlling in common a storage means of a memory cell connecting to a word line receiving a selection signal. CONSTITUTION:Write information is given to a ferroelectric capacitor 3 via a transistor (TR) 1-1 connecting to a word line W1 and a bit line B1 and write operation is implemented, then a clock pulse is given from an address decoder 4 to a drive line D1 from an address decoder 4 and applied also to a capacitor 3'. However, a bit line B2 is at the same high level as that of a readout state, a memory cell connecting to the word line W1 and the bit line B2 applies readout. Thus, when a low level is written in the capacitor 3', the its own polarization of the capacitor 3' is inverted by the readout operation and since the data of the same level as that stored so far is rewritten when the clock pulse is applied, the its own polarization restores and the destruction of a stored data is prevented.

Title: Signal processing circuit for video reproducing device
Inventor: KUDO YOSHIMICHI
IPC: G11B20/02
Filed: 1986-08-29
Abstract: PURPOSE:To realize the special speed reproduction of a disk recorded in a linear velocity constant system by the use of one field memory and to maintain the phase continuity of a sub-carrier at that time by synchronizing the writing start of a signal to the memory with a third latching output and synchronizing the reading start of the signal with a fourth latching output. CONSTITUTION:After the phase of the writing start signal is set to the vertical synchronizing signal of a reproducing signal, it is further set to a reference horizontal synchronizing signal. The phases of the writing start signal and the reading start signal are set to a reference sub-carrier in which the phase is continuous. Since the reading start from the field memory 11 constantly synchronizes with the reference sub-carrier, the phase of the sub-carrier of the read signal is constantly continuous. Since the writing start to the field memory 11 is synchronized with the reference sub-carrier, even if a video signal is switched from an ordinary reproduction mode to a memory reading mode from the disk, the discontinuity is not produced in the sub-carrier.
